* Ryan Newton has added a larger set of atomic memory primops than were previously available. The code was developed on the `atomics` branch, which is now merged. The set of PrimOps may continue to expand slightly, but for now includes `casArray#`, `casIntArray#`, and `fetchAddIntArray#`. In future work, Carter Schonwald will provide optimized (inline) versions of these PrimOps, at least for the LLVM backend.
